Title: Culture tray for the rooting of young plants
Inventor: DUMMEN MARGA
IPC: A01G9/00
Filed: 2003-03-17
Abstract: This invention relates to a culture tray 1, in particular for the rooting of young plants, with channels 2 that run in parallel and at predefinable distances and serve to accommodate young plants. To enable removal of individual young plants preferably without harming them and to enable relatively economical consumption of water for the young plants it is proposed in accordance with the present invention that the space for each young plant be limited by the sidewalls 3, 4 of the channel 2 and across the longitudinal direction of the channel 2 by partition webs 21, 31. This will, in particular, ensure that the water is directly supplied to each plant space and, moreover, that the plants can be pushed sideways out of the culture tray by pushing out of the culture tray the web and ledge skeletons 20, 30, and the plants are easy to take out, because there are then no sidewalls. The embodiment of the culture tray 1 invention warrants uniform moistening of all existing plant spaces and ensures that even those plants receive enough water that are, for example, partly covered by large leaves of adjacent plants, since the water draining down the elevations 5 flows into each individual plant space.

Title: Process for preparing aqueous dispersions of hybrid polyurethane particles
Inventor: SCHROCK ALAN K
IPC: C08F283/00
Filed: 2001-11-02
Abstract: Dispersions of hybrid polyurethane particles are made using miniemulsion techniques. An isocyanate-terminated prepolymer and a monomer are mixed and dispersed in an aqueous phase to form a dispersion of droplets. All droplets  are polymerized and chain-extended in one step to form hybrid particles containing a polyurethane and a polymer of the monomer. This process provide s a simple method of making hybrid particles, in which particle size and the number of particles is controlled in the mixing step. The hybrid particles often have a coreshell morphology, with the polyurethan being concentrated i n the shell and the polymer being concentrated in the center of the particle.< /SDOAB>

Abstract: L'invention concerne un ensemble tour modulaire destiné à être utilisé pour la mise en oeuvre de procédés d'extrusion de pellicules soufflées, chacune des parties de la tour modulaire présentant des tracés de colonnes/pieds identiques qui permettent de les empiler les unes sur les autres. Chaque module peut comporter des plates-formes de type rectangulaire, des ponts de passage étant disposés autour d'un vide central rectangulaire. Des cages d'escaliers peuvent être construites dans le côté de tous les modules à pont, jusqu'au pont supérieur. Chacune des quatre colonnes verticales des modules à pont comporte des éléments inférieurs plats destinés à venir s'empiler sur la surface du pont du module situé en dessous, ainsi qu'un contreventement transversal latéral. Des ailes de pont à plate-forme de rallongement latéral à jambes peuvent être utilisées lorsque le vide rectangulaire central est agrandi. Les modules peuvent être préformés et transportés sur le site pour y être assemblés rapidement au moyen de pièces de fixation telles que des boulons, et ils peuvent être démontables, ce qui différencie cette tour des tours soudées de type permanent. Ces tours modulaires peuvent comporter des éléments de contreventement réglables pour une meilleure consolidation, de sorte que soient réduits le déplacement latéral, la torsion et les vibrations au fil du temps.

Abstract: A system and method for ablating a selected portion of a contact surface of biological tissue is provided. The system includes an elongated ablation sheath having a preformed shape adapted to substantially conform a predetermined surface thereof with the contact surface of the tissue. The ablation sheath defines an ablation lumen sized to slideably receive an elongated ablative device longitudinally therethrough. The ablative device includes a flexible ablation element selectively generating an ablative field sufficiently strong to cause tissue ablation. Advancement of the ablation element slideably through the ablation lumen of the ablation sheath selectively places the ablation element along the ablation path for guide ablation on the contact surface when the predetermined surface is in strategic contact therewith. The ablation lumen and the ablative device cooperate to position the ablation element proximate to the ablation sheath predetermined surface for selective ablation of the selected portion within the ablative field.

Title: Method and apparatus for estimating the position of a terminal based on identification codes for transmission sources
Inventor: STEIN JEREMY M
IPC: H04B7/26
Filed: 2002-04-24
Abstract: Techniques to determine the position of a terminal under the coverage of a repeater in a wireless communication system. In an aspect, an identification code is transmitted for each repeater and used by the terminal (or a PDE) to unambiguously identify the repeater. The identification codes for the repeaters in the system can be implemented with PN sequences at defined offsets that are specifically reserved for repeater identification. In anoth er aspect, the identification code for each repeater is transmitted using a spread-spectrum signal designed to have minimal impact on the performance of the system and to be recoverable by the terminal in similar manner as for a forward modulated signal. In this way, no additional hardware is required fo r the terminal to recover the identifier signal. In one specific design, the spread spectrum identifier signal is generated in accordance with and confor ms to the IS-95 CDMA standard.

Abstract: A pusher assembly for a delivery system for a self-expanding stent (6) which is delivered by proximal withdrawal of a sheath (4) radially surrounding the stent has a stent pusher element (8) which defines a lumen for a guidewire (2), a pusher strand (16) that extends to the proximal end of the delivery system and bears an end-wise compressive stress during release of the stent. A  transfer shaft (12) links the distal end of the pusher strand (16) to the pusher element (8) and lies side-by-side with the guidewire (2). In a rapid exchange version, an adapter (20) provides two lumens side-by-side, one (22) carrying the pusher strand (16) and the other (14) defining a proximal guidewire part. To the adapter is mounted the proximal end of the stent sheath (4). The system allows modular (14) construction, a tapered tip (4A) on the sheath, and an uncluttered internal configuration which facilitates passage of pulses (F) of liquids from the proximal to the distal end of the system.

Title: Physical layer automatic repeat request (arq)
Inventor: KWAK JOSEPH A
IPC: H04B1/69
Filed: 2002-08-21
Abstract: A physical automatic request repeat system comprises a transmitter and a receiver. A physical layer transmitter, at the transmitter, receives data and formats the received data into packets having a particular encoding/data modulation. The physical layer transmitter contains n channels which transmit the packets and retransmits packets in response to not receiving a corresponding acknowledgment for a given packet. An adaptive modulation and coding controller in the transmitter collects retransmission statistics and adjusts the particular encoding/data modulations using the collected statistics. The receiver has a physical layer n-channel receiver for receiving the packets. The receiver contains an n-channel hybrid ARQ combiner/decoder which combines packet transmissions, decodes packets and detects packet errors. The receiver contains an acknowledgment transmitter which transmits an acknowldgment for each packet, if that packet has an acceptable error rate.  The receiver contains an insequence delivery element which delivers acceptable packets to higher layers.
